What I got from both articles is that the new chips from Intel can beat without problems ARM devices in raw processing power, however, they will kill the battery very quickly (unless the systems is kept under control by the OS).

If they have a OS optimized for hand held use (like MeeGo is supposed to be) I for one would be very interested on this, because there would be a chance to unlock this "overdrive mode" for faster apps (and I would have the hand held plugged to a nearby power socket).
